As grafias não convencionais da coda silábica nasal: análise de dados de EJA

Este artigo trata das grafias não convencionais da sílaba com coda nasal encontradas em textos escritos por jovens e adultos. Para a descrição desses dados de escrita, são consideradas duas complexidades: (i) a fonético-fonológica da sílaba, particularmente do elemento nasal em coda, e (ii) a da representação ortográfica da nasalidade em português. Sob o aspecto fonético, a coda corresponde a uma redução de energia, o que pode tornar os segmentos que preenchem essa posição da sílaba menos audíveis. Sob o aspecto fonológico, a coda pode ser vista como um constituinte não imediato da sílaba cujo preenchimento sofre restrições. Sob o aspecto ortográfico, são três as possibilidades de registro da nasalidade: , como, respectivamente, em campo, canto, maçã. Argumenta-se que as grafias não convencionais analisadas podem ser motivadas pelas características fonético-fonológicas dos enunciados falados (particularmente, da sílaba com coda nasal) e, também, pelas características das convenções ortográficas dos enunciados escritos (especificamente, as convenções para representação da nasalidade da coda). Defende-se que essas grafias não sejam vistas como erros decorrentes da interferência da fala na escrita, mas como pistas da relação constitutiva dos enunciados falados e escritos.

Modeling of multiple cracks in reinforced concrete members using solid finite elements with high aspect ratio

This paper presents a new technique to model interfaces by means of degenerated solid finite elements, i.e., elements with a very high aspect ratio, with the smallest dimension corresponding to the thickness of the interfaces. It is shown that, as the aspect ratio increases, the element strains also increase, approaching the kinematics of the strong discontinuity. A tensile damage constitutive relation between strains and stresses is proposed to describe the nonlinear behavior of the interfaces associated with crack opening. To represent crack propagation, couples of triangular interface elements are introduced in between all regular (bulk) elements of the original mesh. With this technique the analyses can be performed integrally in the context of the continuum mechanics and complex crack patterns involving multiple cracks can be simulated without the need of tracking algorithms. Numerical tests are performed to show the applicability of the proposed technique, studding also aspects related to mesh objectivity.

O discurso sobre leitura na esfera escolar e sua relação com o discurso científico

In this paper, the discourse about reading skills uttered by teachers and students is analyzed. The analyses are supported by the Bakhtin’s studies concerning the discourse that necessarily consider the meaning affected by the sphere of the activity in which the enunciation occurs. The concrete utterance, in this perspective, has its identity in relation to the social values that constitute the conscience of the author and in the ideologies that materialize in the discourse, which is always marked by the constitutive relation between the other person and me. The results indicate the following conclusions: the common sense discourse about reading appears in the answers of the analyzed teachers, which consider their students like bad readers, these professionals also do not recognize the technology as a source of reading for their students. Thus, reading that interests the students is not acceptable in school. The symbolic violence practiced by school appears at the moment that the teacher does not consider the student’s language and the readings that interest them; it also appears when the teacher prevents their students to have new readings; moreover, reading is always unique as it is neither new, nor unrepeatable, so it the plurality of meanings is impossible.
